Stellan Skarsgård's body makeup took 8 hours to apply and 2 hours to remove for every day of shooting. He didn't drink anything and took Imodium pills in order to avoid having to go to the bathroom during shooting days.
Lady Jessica's facial tattoos are the Bene Gesserit litany against fear.
Greig Fraser, cinematographer of Dune: Part One (2021) and Dune: Part Two (2024), suggested to shoot the sequence on Giedi Prime (the Harkonnen homeworld) with infrared cameras to give the skin a translucent texture.
Denis Villeneuve said he will not release any deleted scenes, explaining, "I'm a strong believer that when it's not in the movie, it's dead. I kill darlings, and it's painful for me. Sometimes I remove shots and I say, 'I cannot believe I'm cutting this out.' I feel like a samurai opening my gut. It's painful, so I cannot go back after that and create a Frankenstein and try to reanimate things that I killed. It's too painful. When it's dead, it's dead, and it's dead for a reason. But yes, it is a painful project, but it is my job. The movie prevails. I'm very, I think, severe in the editing room. I'm not thinking about my ego, I'm thinking about the movie."
Feyd-Rautha's fight on Giedi Prime is seen in a black-and-white infrared color palette, apparently induced by a black sun that the planet orbits around. This is the first time the Giedi's sun is shown in a Dune adaptation. However the description in the book of a "planet of the black sun" is likely to be metaphorical, as all stars emit light, and a planet receiving no light would not be able to sustain life.
